teff into wheat stubble

looking for advise on planting teff into wheat stubble. I have a broadcast spreader which is how i plant my home farm. has anyone had luck with spreading over stubble before a rain ? I can work the ground but it always seems like the soil is to loose and I never really get a good stand when I do that .

This year I worked ground and cultipacked before seeding. Then I ran the packer with a chain behind it - not a lot of rain - reall bad stand this year. I think I should have left the chain off and just used the packer - oh well next year right ?

A couple of years ago I ran some teff into a poor stand of alfalfa. I just used a drill with grass seeder attachment and covering chains. It turned out to be a decent stand. I wanted to put some teff into wheat stubble this year but didn't have the moisture. I was just going to use the Brillion and not work the ground.
